PSU--> eep. the psu you selected is ultra expensive, you might consider the far better rated brand: 'pc power and cooling' you might consider looking at one of the few high-efficiency 90PLUS rated psus...
CASE/Cooler-> Take a peek at the RCS100 case. It offers refrigeration for the cpu -- at $10,000, you need to have something exotic. If not refrigeration, the CoolIT Boreas 12 is the highest rated non-painfully-custom cooling solution. you can order it for one cpu, two cpus, one gpu, two gpus, etc. the antec twelve hundred is a terrific case, very tall though. I have five HDs in raid0 and two graphics cards in my antec nine hundred, and it still isnt full. I replaced all the antec stock fans with nice quiet variable speed ones -- fans, fan silencers, psu silencers, noise reduction padding inside the case, i dont see any of that listed...
MONITORS-> 30s are huge, did you look at (26inch?) the 120hz models with the glasses as an alternative?
RAM-> good ram, but the reviews of the included fan are terrible. buy the version w/o the fan. Also, 12gb won't likely give you any improvement over 6gb. you wont max out 6gb no matter what you do....
VID-> the FTW is awesome (I have it), although if going with multiple cards, i think the single gpu 280 is a better choice (faster) than the dual gpu 285. check toms, buy i'm 99% sure that the reviews show that having two 280 single gpu cards are faster in most games than two 285s (four gpus).
RAID->a raid card will likely help speed up your system, Raid0 on your ssd drives with the card, and raid0 on the 7200 drives using your motherboard sata connectors...
